| titleOfInvention | Polyurethane elastic resin containing diaminodiphenyl ether structural unit |
| abstract | The invention relates to polyurethane elastic resin containing a diaminodiphenyl ether structural unit and a preparation method thereof. According to the invention, cyclic carbonate reacts with diaminodiphenyl ether to convert terminal amino into hydroxyl, and caprolactone is used for chain extension to synthesize hydroxyl resin, and as a urethane bond with good mechanical property is formed in the reaction, and the flexibility is improved after chain extension, the prepared polyurethane elastomer containing the diaminodiphenyl ether structure has good mechanical property, the service life is greatly prolonged, and the polyurethane elastomer is beneficial to construction and application. |
